Power Supply Controllers, Monitors Procurement Notes

Verify the obsolete status and Not Recommended for New Design (NRND) classification before integration into new products. Confirm that the SOT-23-6 package availability aligns with long-term supply requirements. Ensure design-in decisions account for potential end-of-life constraints associated with this specific part number.

Power Supply Controllers, Monitors Selection Notes

Select this component for flyback applications requiring a 200 kHz switching frequency and isolated output. Consider the SOT-23-6 package for space-constrained designs. Evaluate the 2.8 V to 6 V supply range against system power architecture. Note the NRND status when planning for future production scalability or extended lifecycle support.

Power Supply Controllers, Monitors Part Context

This component belongs to the FAN6290 series of power management ICs from onsemi. It is categorized under switching controllers within the PMIC portfolio. The MEMX suffix indicates the specific tape and reel packaging variant. It shares functional similarities with other flyback controllers but is distinct in its pinout and specific electrical parameters.

Power Supply Controllers, Monitors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on compatible flyback topology, similar switching frequency, and equivalent package dimensions.
